Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2522, here are decompositions:

19 + 2503 = 2522
139 + 2383 = 2522
151 + 2371 = 2522
181 + 2341 = 2522
211 + 2311 = 2522
229 + 2293 = 2522
241 + 2281 = 2522
271 + 2251 = 2522

Showing the first eight; more decompositions exist.
